To all 'whom t may concern Be it known that l, GEORGE H. lsLnY, a

citizen of the United States, residing'at Worcester, in the county ofworcester and Com'- monwealth of Massachusetts, have invented a new andusefulA Improvement in a Valve, ,y of which the following, together'with accompanying drawings, is a specification.

The present invention relates generally to valves or dampers such as areused in flues or conduits for the passage of gases, las for instancefurnace flues or the4 like. Therin# vention relates particularly totheprovision of `a valve or damper which, in closed position, is adaptedmore .effectually than the valves or dampers now in ordinary use to shutoif the flue or conduit and prevent the passage of gas therethrough.'Fo-this end the valvestructure is adaptedv to cooperate with abodyoffwater' in such a manner 'as to constitute, in its closedposition, an effec# tive water sealagainst thevescape of gases pastthat-pointin the Aflue where'- the valve is located, thus aifordingmarked advantages over thesand Seal and other cut off devices orvalveswhich are now in ordinary u se. 4

-Th'e principles of the invention are fully set Vforth hereinafter,reference being had to the' accompanying drawingsk which illus-v trateYseveral-embodiments thereof, and in` fisthus adapted to Amove/in anoscillatory which drawings Fig.L 1 yis a-view in. elevation ofa flue lorconduit with the invention appliedthereto',

l is embodiedin a suitably supported conduit or passage 2y directlykabove the same,

the'arrangement being such vthat normally there'will be a ycontinuousflowjof gas through theflue's l and 2,"in the direction of arrow-il.` lU To rthis end there is disposed between the' l adjacent ends of thefluesland 2 a receptacle l I or casting. 3, having' an interior passagethat takes the gas directly fromv the. iue l. The passage 4terminatesjust vshort ofl the passage vor flue' 2,. for arpurposehereinafrllheendof passage or flue pending skirt `or flangey 5, which-atalltimes dips below the surface of 'a bodyV ofwater carriedbythereceptacle 3 and completely Q'has a defi surronndingthe upper end ofypassage 4. In *y this'way, in spite of the gap 'left 1between thepassagesV 2 andl, there is always agas tight connection between themsincev there.

is no possihilityfor any gas to escapepasty the skirt 5 as long as thelatterdips into i the annular body of water ingreceptaclei The gapAbetween the passages?, and-4; `al- -lows thefree movement betweensaid"pas sages ofv a valve or damper 6, which is here shownv asSupported by rocking-arms l7 that are journalled at 8 between thepassage .4 and theiouter wall of receptacle 3. The valvedisposed'whollyat one side of the passage Il, so asnot to obstructthetravel of gas from the flue l to the flue 2,-the valve Gibeing im-gyf mersed, for the most part, inthe .watenat one side ofthe receptacle 3.f When the lever -9 r is moved tothe right in Fig. 2, the arms 7areswung-about their. pivots into; an upright position, thus carryingthe valve 6 into the 'l gap between the passages 2y and 4,diret :tlyy

over the joutlet yof passage Vil. In this position l the valve, byreasonof its curvature and by YVreason of its depending skirt 10, provides awater seal entirely surrounding the openend l of passage l, and withinthe water seal provided bytheskirtor flange-5. As a result,` the exitofgas fromthe assage l is eilectu vallyandpositively out o' andA alllcommunilt is to be noted that the travel ot theI valve is in a circularpath, about the axis of the arms T, and that this path, where itintersects the surface of the water in receptacle 3, is within the'space inclosed by the depend ing water seal skirt 5. To render easierthe movement of the valve to its closing position, the weight ot thesame may be partially counterbalanced, if cesired. by a counterweight 11attached by a flexible connection 12 to the lever 9. To insure themaintenance ot'suiiicient water in the receptacle an. overflow partition13 thereof is extended well above the lower edge et skirt 5, and alsowell above the edge of valve G when the latter is in closed position.Such position may be determined by the engagement arm .7 with a stop14e, or in any other' suitable manner.

To permit access to the valve 6, for the purpose of withdrawing orrepairing the same, the iiange or skirt 5 has a removable section 15disposed above that part oi the receptacle 3 which theV valve occupieswhen. in open position. By removing this section 15, the valve may bewithdrawn bodily with out diiiiculty, and if desired, a new valve maybey put in its place. fis an alternative to this arrano'ement, theconstruction oic Fig. 3

mayy be adopted7 this construction involving water receptacle 3 ofsuihcient depth to allow the valve 6 in its inoperative position.y to belowered entirely past the flange or skirt 5. ln the construction of thedow o gas is in the opposite direction to that illustrated in Figs. 1and 2. being in the direction of arrow B, 'from the flue 2' into theline 1. The principle oit operation. howover, of the valve 6 and itscooperating water seal instrumentalitics is precisely the same in thetwo eases, as will be apparent. Said valve 6 oiL Fig. 3 when movedl intoclosing position. forms a water seal around the end ot interior passage4 and eftectually prevents the entrance of any gas into said passage.The surrounding skirt 5 ot flue extension 16 cooperates with the waterin receptacle 3 to prevent any escape of gas outwardly. ln Figs. 1 and 2the tlue extension oipassage el. is etlectually water cooled by thesurrounding water of receptacle in Fig.. 3, the flue extension 16 maybecorrespondingly cooled by a surrounding' water chamber 17,

The size of the parts entering into the construction oie the valve isreduced in Figs. 1 and 2 by contracting the passage l inthe di rectionof travel ot the gas, and thereafter expanding; to normal cross sectionin the passage 2. The saine principle is involved in the construction ofFig. by contracting tho flue extension 1G and then allowing the gas toexpand in the passage l andin the flue l. However. this arrangement or'parts not essential to the invention, since obviously the arrangement oiflue passages shown in Fig. 4 u'iay readily be adopted, without greatlyincreasingthe size of the valve. In the construction o'l: Fig. l. theflue passages lo and 19 `are uni'torm in cross section throughout, thepassage 19 beingsurrounded by water re ceptacle 2O into which dips theskirt 2l. The water receptacle 2O is made deep enough to receive thevalve 22 on either side ot its axis 23, and consequently said valve isadapted to be communication between by moven'i'ent in either directionabout its anis. ,'"iccessto the valve is obtained by removing thesection 24 of the skirt 23.

The several constructions shown are obviously susceptible of widevariation in the manner or adapting them to different types of ilues orconduits, without departing from the spirit of the invention as setforth in 'he annexed claims, lt will be seen that the the lines 1S and19 same as an ordinary damper; when entirely all possilnlity ot leakagepastA the clos@ i., val is eliminated.

A inodiiied `form of valve, which is ap# plicable under certainconditions, is illustrated in Figs. 5 and 6, wherein. a flue or passage25, through which thegas'uiiows in the direction oit arrow C, is sho-wnas pro-y The upper edge of passage 29 presents ak smooth iinishedannular surfacev or seat 31; lor cooperation with this'seat, a dat valve30 having` a tinished under surface, is pro,-

opened tov establish vided, said Avalve 'being pivoted on a pin l 33'which projects upwardlyfrom the bottom of casting 28.. The valve 32 hassecured thereto a. handle Se, which'is Jcurved'"do-tvnwardly beneath theskirt 27,' and thence passes upwardly in positionto be seized by theoperator, When in closed position, the

valve eti'ectuall'y shuts off they passage of gases through the tlues2,5, 26, and when moved into open position, as shown bv dotted lines inFig. 6, a clear passage through said fines is afforded. The manipulationof the valve is accomplished bythe handle 34 which projects through andbeyond the water seal elements, and it' is 0b- Vious that thecontraction of the passage and the cooling of the valve seat by thesurrounding water enables the valve to oper-v ate .with entiresatisfaction under the condi-` tions assumed, viz, with the gas flowingin the direction of the arrow C. The casting 28 provides a bearing lug35 Jfor the support 1 ofV valve 32, when the latter is moved 'into openposition.

I claim,
